CPU Smart Fan Control on the 8KNXP
The manual says that the CPU Smart Fan Control, when enabled, will run
the fan at low speed when the CPU temp is below 40C and high speed when the temp is over 40C. The problem is that whenever I first turn on the computer, the temperature always starts at 40C and goes up from there. I have never seen it lower even though the ambient temp is well below that. Anyone else have this problem? Solutions? Dave |

If you have a retail P4 the HS&fan that comes with it has a temp monitor
built in and its best to disable the smart fan option in bios as the fan regulates its own temp speed. "David D." wrote in message om...

Depends on what CPU you have. I have a 3.2Ghz, and it's never below 41
although it also never goes beyond 57c fully loaded at constant 100% utilization. "David D." wrote in message om...

I think you're right about the temperature sensor being built-in, but
there is no connection between the chip and the fan, thus no way for the chip to control the fan speed. So this doesn't make sense to me. Dave "The Marshal" wrote in message ...

I don't think it's a case of my 2.6Ghz running hotter than other chips
since 40C is always the temperature that it starts at, even after a completely cold start...and it sounds like your 3.2 does about the same. It seems that the chip always reports 40C and then goes up from there regardless of the ambient temperature. So it would apprear that for the lot of us the smart CPU fan control is pretty useless unless I can set the speed at which it engages. Is there anyone out there who can report this feature actually working? Dave "Timothy Drouillard" wrote in message ... Depends on what CPU you have.

Hello David
I just built a system up with a new Thermaltake Xaser III aluminium case. Upon doing this the 7 fans on this case were inoperable initially and the CPU temp was 40C and the CPU kernel temp about 72C. However now that the fans are up and working the CPU temp is actually 31-32C, CPU kernel temp is 69C and the CPU fan is listed at 2700 rpm. Even under load this system only changes about 1 to 2 degrees. Current room temperatures are quite low, about 18C, as it is winter here in Oz. However even in summer this should still be quite low as I currently have most of the fans on low speed. I have personally found that aluminium cases definitely help reduce overall temperatures. In addition the Li Lian PC60 case and this Thermaltake I have both have top fans which I do believe help signifircantly in removing the hot air from the case. I have a lot of gear in this case like 4 IDE RAID disk (0+1) which sit at about 20C BTW. So I would think that your case is not well ventilated or may require some additional cooling fans. The 40C is not really a problem though from what I understand as it will run up to about 60C without problems. However as you can see from my example a few case fans can make a significant difference to the CPU temps as well. Regards Mark "David D." wrote in message om...

Thanks for the response, but cooling is not the issue here. The
temperature is 40C immediately upon an initial cold boot of the machine (which *is* aluminum and has plenty of ventilation). For example, if I leave the machine overnight, come to it in the morning, turn it one and immediately go into the bios (all within 20 seconds), the temp is always exactly 40C even if the ambient temperature is well below that. If I then leave the machine running, the temp slowly creeps up as expected, but not to any temp that would cause a problem (highest has been around 45C so far). Remember, I'm not concerned here about problematic temperatures since I'm not seeing that; my *only* issue is noise and the "smart" fan control that doesn't seem to have any practical value. Has anyone here gotten the smart fan control to work on this board? Dave "Mark Taylor" wrote in message ... Hello David I just built a system up with a new Thermaltake Xaser III aluminium case.
